The number of MOT failures are rising dramatically following test changes that came into force earlier this year, new research suggests.
Data taken from 50 test stations across the country in the last three months found failure rates for petrol cars have risen by 12 per cent, while the number of diesel motors failing has risen by 24 per cent.
The study, conducted by Prestige Motor Warehouse, found emissions to be the biggest problem for diesels.
The changes saw one of the biggest shake-ups to the MOT test by the DVSA since it was first introduced.
A representative from prestigemotorwarehouse.co.uk, said: “There are stricter limits for emissions from diesel cars with a diesel particulate filter (DPF).
“This has seen a big increase to the failure rates over the past three months – but it is not surprising to hear and read.”
The failure rate has also seen a rise in the number of cars written off entirely.
A spokesperson at Scrap Car Comparison said: “There’s more and more of the older cars failing the new MOT and that has led to an increase in the calls we are getting for people wanting to scrap their cars.
“More people are now buying eco-friendly cars and on finance and this is leading to less of the older polluting diesels on the roads.”
